Wipe via black with glow makes it white without glowing
This glow works differently, even to other screenspace glow settings like the text gadget.
Right. This is inconsistent with the rest of Dreams and so is confusing if you're trying to learn how stuff like this behaves.
I guess I'll post this as feedback again.

Thank you for the feedback, however we can confirm this is not an issue. When setting glow to 100% the effect overpowers everything else and wipe effect is a change to white colour.
